SHIP CONSTRUCTlON-' To all whom it may cancer-i2:

Be' it known thatwe, GEORG MITCHELL HARrtowAr and \Varximx' DIXON; sub'ects of the 'King'of Great Britain and Irelanfi, re-

siding. at Middlesbrotigh, in thecounty of.

York,.England,-have invented Improvements in Ship Construction, of which the following is a specification.

In the specification of another application for Letters Patent, filed January13, 1905,-

Serial No. 240,904, we have described an improved ship construction wherein-the fram 1ng comprises cantalive'r-franies in each of which, toform the cantaliver, there are two upwardlyextending branches--namel a continuous outer, bra'n'cn'to Which'the Sklnbf a the vessel is riveted and the inwardly-provjecting flange of which has formed in it a gap branches, a suitably-supported deck portion connecting the fore-and-aftplating to the lates between the branches of the several rames, forms a boxgirder that gives greatjlongitudinal strength to the ship.

Now in the building of ships of the type referred to according to the present invention r .'the lower'portion and one of the branches of 'each' cantalivereframe are constituted by a continuous bar,which is hereinafter called the maln bar, (which may be a bulb angle-bar or its e u1valent+such as achannel-bar, Z-f

bar, or ulb T-bar,l and the other branch of the frame is formed by a separate bar rigidly 'scarfed or riveted to said lower portion of the mainbar, so as to constitute an integral porvg-tlon of the cantahver-frame.

Referring to the accompanying illustral view of a portion of a ship provided with cantive dranings, Figure ,1 is acrosssectional .taliver-frames, according to this'invention,

* Fig, .1 of the upper port-ion of the frame Fig. 2 is an elevation taken at right angles to shown.. Fig. 3 is a horizontal section correspond1ng.,.to. the line A B of Fig. 1. Figs. 4

The lower upright portion a and the inwardly-inclined branch b of the frame show'n in Fig. 1 instead of being formed by a framebar'and a reverse bar or an equivalentlyformed part are ,formed -by a main bar a b, which is'a continuous bulb angle-bar of'sufficientfstrength in its portion a to take the placegofbotfh a frame-bar and a reverse bar andi's'simply bent inward at the required partfin order to form the inner portion of the cantaliver, aiid the outer branch col the frame, the inwardlyprojecting flange of which has a gap" dito receive the stringer-bar e,-is formed by a separate angle-bar, which is scarfed orriveted at f to the portion a of the main bar a b, was toconstitute an integral portion of the cantaliver-frame. Suit-able. packing material is or may be placed at g between theshell-platingh and the bars a and c.

In the frame shown 'in Fig. 7 the lower upright portion aand theouter branch 0' of the frame, which has thegap d toreceive the stringer-bar e, are both formed by a main bar a c, which is a continuous-bulb anglebar, which, like thatshown in Fig. '1', is of suflicient strength in its ortiona to take the place of a frame-bar and a reverse bar, while the inner branch bof the cantaliver-frame is formed by a se arate angle-bar wnich is scarfed or rivete' at 0' to the-portion a of the r main barfa 0, so as to constitute an integral ortion of the cantaliver-frame, and" is bent inwardly at the: required part in order to form' the inner portion oft-he cantaliver.
